Electricity, Natural Gas, and Emissions

National Instruments conserves resources through its facilities and IT infrastructure by reducing energy consumption, greenhouse gas emissions, water use, and waste, as well as increasing recycling. As part of these efforts, NI subscribes to Austin Energy GreenChoice, a renewable energy program, to provide 10 percent of the total electricity usage at its headquarters.

Electricity

Purchased Electricity Used per Employee¹

Total purchased electricity increased in 2011 due to a 16 percent increase in the number of employees worldwide.

Emissions

Reducing Emissions

NI is a member of the Clean Air Partners Program (CAPP) of Central Texas, a coalition of industry and civic organizations that encourages businesses to reduce air emissions by 10 percent over three years. The program promotes clean air business practices, such as employee carpooling, renewable energy, and water conservation techniques. As a member of this program since 2004, NI reports annually to the organization on emissions and reductions achieved. In 2010, NI reduced emissions 2.94 percent per employee compared to a baseline measurement in 2009. The 2011 data is not yet available from the program.

The following tables present data for only Scope 1 and limited Scope 2 emissions, which include those from natural gas, purchased electricity, and operation of company-owned vehicles.
